ScerGAL4cb24 drives expression in the embryonic lymph glands and CNS, in the larval central nervous system, in all imaginal discs, and in circumferential rings around the adult testis. During oogenesis, ScerGAL4cb24 drives expression in terminal filaments and/or female germline stem cells, in anterior nurse follicle cells (stretch cells), in two clusters of cells on either side of the dorsal anterior midline of the egg chamber, and in random, posterior follicle cells.
